Random misfire comes and goes help I bought a 99 z28 and it's missing after it warms up it gets better and better then it will go away run great and it will come back. Its very irritating I haven't changed the plugs and wires yet just wondering if anyone has seen this before. Coil or computer problem maybe intake gasket?
